It is understood that fixed-height table 100 may also be communicatively coupled to mobile device 270 in a similar fashion, but certain details described in Figure 10 may not apply to a fixed-height table (e.g., instruction to switch to a standing mode).
- Computing device 214 may receive pressure readings from pressure sensors 208a, 208b, 208c and 208d and/or a signal from gyroscope 210. Based on such detected sensor signals, computing device 214 may determine, using machine learning, a posture of the user. The use of machine learning is described in more detail in Figure 11. In the illustrated example, the determined posture is then determined to deviate from a proper ergonomic position. As a result, a message to straighten the user’s back is transmitted from computing device 214 to mobile 270 and displayed thereon.
- computing device 214 determines that the user has been sitting for more than one hour (e.g., there has been intermittent pressure on one or more of the pressure sensors for the last hour and the table is in a lowered position, implying a seating position). As a result, a message to switch to a standing mode is suggested to the user (i.e., suggestion to raise the height of the table).

- pressure pattern 1 is paired with an identification of a proper ergonomic position 1 (output); pressure pattern 2 (input) is paired with an identification of improper ergonomic position 1 (i.e., slouching back) (output); ... and pressure pattern 5 (input) is paired with an identification of improper ergonomic position 3 (i.e., bent wrists) (output).
- parameters of the machine learning module are optimized (e.g., via a backpropagation algorithm).
- the machine learning module may be used to evaluate the posture of the user based on detected pressure patterns (i.e., in a model application phase).
- a feedback module (abbreviated as FM) is also present, which takes the inferred posture from the machine learning module and determines an appropriate remediation measure (or if no remediation is needed, then compliments to the user on his or her proper posture).
- the machine learning module infers improper ergonomic position 1 (slouching back) based on pressure pattern 22 (which has some similarities to pressure pattern 2), and the feedback module determines the remediation measure of“Straighten your back” as a proper remediation measure for improper ergonomic position 1.
- the machine learning module infers proper ergonomic position 1 based on pressure pattern 31 (which has some similarities to pressure pattern 1), and the feedback module determines that words of encouragement (e.g.,“Well done, good posture!”) to the user are proper based on the user’s proper ergonomic position.

Description
A TABLE WITH ONE OR MORE TAP GESTURE- ACTIVATED LIGHT
INDICATORS
RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Application No. 62/878,155, filed 24 July 2019.
FIELD OF THE INVENTION
[0002] The present invention relates to a table with one or more tap gesture-activated light indicators, and more specifically relates to a table with one or more tap gesture-activated light indicators indicating a location of one or more wireless charging areas on the table and a tap gesture-activated light indicator indicating a location of one or more control elements for adjusting a height of the table.
BACKGROUND
[0003] Tables are an integral furnishing of any work or home office. Prior to the digital revolution, tables in a work or home office were primarily used as a writing or reading surface. Ever since the digital revolution, tables have increasingly been used as a workspace on which various electronic devices (e.g., a computer monitor, laptop, desktop, smartphone, keyboard, etc.) are placed or are used. The basic function of a table as a supporting surface, however, has not evolved much at all despite the digital age.
[0004] Discussed herein are various improvements to tables to better accommodate the use of electronic devices in the work or home office.
SUMMARY OF THE INVENTION
[0005] In accordance with one embodiment of the invention, a table may include one or more tap gesture-activated light indicators that appear on a top surface of the table. One or more sensors (e.g., a vibration sensor, a pressure sensor) may be disposed within or proximate to the tabletop for detecting the tap gesture performed by a user on the top surface of the tabletop.
[0006] The one or more light indicators may indicate a location of one or more wireless charging areas on the top surface of the table, which may be disposed above one or more wireless chargers that are located immediately below the top surface of the table. The one or
more wireless chargers may be used to charge a battery of a mobile device (e.g., mobile phone, etc.). The one or more light indicators may also indicate a location of one or more control elements disposed on a bottom surface of the table. That is, the X-Y location of a light indicator on the top surface of the table can guide a user to a corresponding X-Y location on the bottom surface of the table where the control element is located. The one or more control elements may be configured to raise the height of the table, lower the height of the table and/or enable or disable the tap gesture sensors (e.g., to save power when the table is not being used overnight).
[0007] The table may additionally include one or more universal serial bus (USB) outlets, in particular a USB-C outlet, disposed on a surface of the tabletop. The table may additionally include one or more power outlets disposed on a surface of the tabletop (e.g., for powering a laptop, monitor, etc.). One or more of the power outlets may be disposed adjacent to or above one or more of the legs of the table, allowing liquid that is spilled into the one or more power outlets to drain from the one or more power outlets through one or more of the legs of the table. The table may additionally include a gyroscope configured to determine whether or not the tabletop is level. The table may additionally include a coupling mechanism (e.g., magnetic coupling) disposed on a bottom surface of the tabletop that is configured to releasably couple with a hook (e.g., for hanging a handbag, backpack, etc.).
[0008] The tabletop may include an acrylic stone exterior and an internal cavity within the acrylic stone exterior. A bottom surface of the tabletop may include a removable panel that, when removed, exposes a grid frame disposed within the internal cavity. Various components (e.g., wireless chargers, pressure sensors, gyroscope, etc.) may be secured to the grid frame.
[0009] In one embodiment of the invention, the table is height-adjustable and includes a plurality of height-adjustable legs. Each of the height-adjustable legs may include a linear actuator and a telescopic enclosure. The linear actuator may include a nut with an invariant vertical elevation, a screw shaft that is screwed through a central opening of the nut, a motor configured to rotate the screw shaft about a rotational axis of the screw shaft, an inner tubular enclosure that is fixedly secured to the nut, and an outer tubular enclosure that is fixedly secured to the motor. Rotation of the screw shaft may cause the outer tubular enclosure to vertically translate (e.g., upwards or downwards) with respect to the inner tubular enclosure. The telescopic enclosure may enclose the outer tubular enclosure. In one embodiment, the telescopic enclosure may include a plurality of bulbous members.
[0010] In one embodiment of the invention, a pressure sensitive surface of the table may measure a pressure pattern generated by one or more of a hand, forearm or elbow of the user resting on the pressure sensitive surface, and a machine learning algorithm may be used to infer a posture of the user based on the pressure pattern. In response to determining that the posture of the user deviates from an ergonomic posture, an alert may be transmited to the user, informing the user of the deviation from the ergonomic posture. The alert may be in the form of a tactile alert (e.g., vibration of the table) and/or a message displayed on a display device of the user (e.g., the message informing the user of the deviation from the ergonomic posture). In response to the posture of the user deviating from an ergonomic position, the display device may additionally display a message that suggests the user to take a corrective measure (e.g., raising a height of the table, lowering the height of the table, working in a standing position and/or sitting in an upright position).
[0011] These and other embodiments of the invention are more fully described in association with the drawings below.

DETAILED DESCRIPTION OF THE INVENTION
[0037] Figure 1 A depicts a top perspective view of fixed-height table 100 in a non- illuminated state. Fixed-height table 100 may include tabletop 102 that is supported by two or more legs. In the embodiment depicted in Figure 1 A, tabletop 102 is supported by four legs 104a, 104b, 104c and 104d, each positioned near a comer of tabletop 102. Tabletop 102 may include an acrylic stone exterior with an internal cavity (not visible in Figure 1 A). The acrylic stone material has numerous advantageous properties, including being water resistant, scratch resistant, heat resistant (i.e., resistant to damage when a hot cup of coffee is placed onto the surface of tabletop 102), etc.
[0038] Tabletop 102 may include one or more power outlets. In the embodiment of Figure 1A, the top surface of tabletop 102 includes universal power outlet 106a (capable of receiving electrical plugs adhering to European standards as well as US standards), and universal serial bus (USB) outlets 106b and 106c. More specifically, USB outlets 106b and 106c may be USB-C outlets. It is noted that universal power outlet 106a may be disposed adjacent to or above leg 104b, allowing liquid (e.g., coffee) that is spilled into universal power outlet 106a to drain from universal power outlet 106a through leg 104b.
[0039] Tabletop 102 may include one or more wireless charging areas located on a top surface of tabletop 102. When a mobile device (e.g., a smart phone, a tablet, etc.) is placed within or near the wireless charging area, a wireless charger disposed immediately beneath the wireless charging area is configured to wirelessly charge a battery of the mobile device.
In the embodiment of Figure 1 A, three wireless charging area 108a, 108b and 108c are present on tabletop 102. The respective outlines of the wireless charging areas are depicted in broken line in Figure 1 A to reflect an embodiment of the invention in which the respective boundaries of the wireless charging areas are not marked on the top surface of tabletop 102 (e.g., for aesthetic reasons). It is understood that the number of wireless charging areas may differ in another embodiment of the invention.
[0040] Figure IB depicts a top perspective view of fixed-height table 100 in an illuminated state. Upon a user performing a tap gesture (e.g., single tap, double tap in rapid succession, etc.) on a surface of tabletop 102 (e.g., the surface described later in more detail as a pressure or touch sensitive surface), one or more light indicators may appear on the top surface of tabletop 102. It is understood that a tap gesture is merely an example of a human- based gesture that could be used to turn on the one or more light indicators. Other gestures may include a swipe gesture, a check gesture, a gesture that draws a shape or symbol on the
surface of tabletop 102 (e.g., draw circle, draw plus sign, etc.).
[0041] One or more light sources (not depicted in Figure IB) may be present immediately below the top surface of the tabletop and shine light through a translucent (or transparent) portion of the top surface of tabletop 102 to generate the light indicators. In the embodiment depicted in Figure IB, three light indicators 110a, 110b and 110c are present to indicate the location of wireless charging areas 108a, 108b and 108c, respectively. In one embodiment, each of the light indicators appears as a“+” symbol on the top surface of tabletop 102, but it is understood that other symbols, and shapes may be used instead of the “+” symbol. While the light indicators indicated the location of the wireless charging areas in the embodiment of Figure IB, light indicators may indicate other features of table 100, as will be described in the subsequent figures.
[0042] Figure 1C depicts a bottom view of fixed-height table 100. A bottom surface of tabletop 102 may include removable panel 118a and fixed panel 118b. Removable panel 118a may be secured to tabletop 102 using screws (not depicted). When removable panel 118a is removed from table 100, an internal cavity of table 100 may be accessed. The contents of the internal cavity will be described in Figures 2A and 2B below.
[0043] A bottom surface of tabletop 102 may also include additional power outlets. In the embodiment depicted in Figure 1C, two universal power outlets 106d and 106e are present. Power outlets 106d and 106e may be convenient for plugging in the power cable of a monitor and the power cable of a laptop or desktop computer. In between power outlets 106d and 106e may be an internal electrical port 112, used to supply power to various internal electrical components of table 100.
[0044] A bottom surface of tabletop 102 may also include coupling mechanism 114 (e.g., a magnetic coupling mechanism) to releasably secure a hook to a bottom surface of tabletop 102. The hook (not depicted) may be a convenient accessory for a user to hang a backpack, handbag, scarf and/or hat underneath tabletop 102. An advantage of a magnetic coupling mechanism (as opposed to other coupling mechanisms, such as using screws to attach a hook to the bottom surface of tabletop 102) is the ease of assembly (i.e., no screw driver or hand-held drill is needed).
[0045] A bottom surface of tabletop 102 may also include control element 116 for enabling and disabling components involved with the sensing the tap (or other) gesture. For instance, to save power upon finishing the use of table 100 (e.g., when leaving the work office to return home at the end of the day), a user may press control element 116 to disable
components involved with the sensing the tap gesture. Upon resuming the use of table 100 (e.g., when returning to the work office the next day), the user may press control element 116 to re-enable components involved with the sensing of the tap gesture.
[0046] Figure ID depicts a bottom perspective view of fixed-height table 100. The components that are visible in the bottom perspective view of fixed-height table 100 are identical to the components that are visible in the bottom view of fixed-height table 100, so no additional description will be provided in association with Figure ID for conciseness.
[0047] Figure IE depicts a sectional perspective view of fixed-height table 100 with a cutting plane perpendicular to the plane of the top surface of the table. Cavity 120 is visible in the cross-sectional surface exposed in the sectional perspective view. Cavity 120 may include frame 122, which may be a grid made from a rigid material, such as aluminum.
Frame 122 may provide structural integrity to tabletop 102 (e.g., preventing warping, bending, sagging, etc.). The rounded edge of tabletop 102 is visible in the cross-sectional surface exposed in the sectional perspective view. The rounded edge may allow a user to more comfortably rest his or her elbows on tabletop 102 when using a computer keyboard.
[0048] Figure 2A depicts a top cross-sectional view of tabletop 102 (i.e., cross-section of tabletop 102 when viewed from the top), in which various internal components of tabletop 102 are visible. Frame 202 (e.g., in the form of a grid) may be present within the cavity of tabletop 102. Anchored to frame 202 may be power board 204 with power socket 106a and USB ports 106b, 106c. Also anchored to frame 202 may be power board 206 with power sockets 106d and 106e, and internal electrical port 112 Also anchored to frame 202 may be one or more pressure sensors. In the embodiment depicted in Figure 2A, four pressure sensors 208a, 208b, 208c and 208d may be present, but it is understood that additional pressure sensors (not depicted) may be present. While pressure sensors are depicted as being located in cavity 120 of tabletop 102, it is noted that in another embodiment (not depicted), the pressure sensors could instead be located on a top surface of tabletop 102 (or could be embedded into the acrylic stone exterior). Also anchored to frame 202 may be gyroscope 210, which is configured to sense vibrations and the position of table 100 (e.g., whether the table is level, wobbling, etc.). Also anchored to frame 202 may be taptic engine 212, which is configured to output tactile stimuli (e.g., vibration) that may be felt by a user’s hand and/or finger on a surface of tabletop 102. Also anchored to frame 202 may be wireless charger 220, which is configured to wirelessly charge a battery of a mobile device placed on or near wireless charging areas 108a, 108b and 108c. Also anchored to frame may be computing
device 214 with vibration sensor 216.
[0049] As depicted in schematic drawing 250 of Figure 2B, computing device 214 may be communicatively coupled to various electrical components of tabletop 102. Computing device 214 may be configured to receive an on/off signal from control element 116. For example, a waveform (e.g., pulse waveform) from control element 116 may cause computing device 214 to be powered on. Likewise, a waveform (e.g., pulse waveform) from control element 116 may cause computing device 214 to be powered off. Computing device 214 may be configured to receive pressure readings from one or more of pressor sensors 208a, 208b, 208c and 208d. Such pressure readings may be processed by computing device 214 to determine the occurrence of a tap gesture (or other gesture) performed by a user on tabletop 102. In response to detecting the tap gesture, computing device 214 may power on wireless charger 220 (and the light sources depicted in Figure 3). Pressure readings may also be processed by computing device 214 to determine a posture of user (e.g., whether a proper ergonomic position or an improper ergonomic position). Upon the determination of an improper ergonomic position, computer device 214 may transmit a signal to activate taptic engine 212, in turn generating a vibrational alert to notify the user of the improper ergonomic position. In another embodiment, upon the determination of an improper ergonomic position, computer device 214 may wireless transmit a message to a display of a mobile device (e.g., laptop, smartphone, etc.), the message alerting the user of the improper ergonomic position. Optionally, a remediation measure may also be displayed, such as“Please sit up!”
[0050] In addition to or instead of using the pressure sensors, vibration sensor 216 may also be used to detect a tap-gesture, and in response to detection of the tap-gesture, computing device 214 may power on wireless charger 220 (and the light sources depicted in Figure 3).
[0051] In addition to or instead of using the pressure sensors, gyroscope 210 may also be used to detect a tap-gesture, and in response to detection of the tap-gesture, computing device 214 may power on wireless charger 220 (and the light sources depicted in Figure 3). Gyroscope 210 may also transmit a position-related signal to processor 214, allowing processor 214 to determine and report to a user whether table 100 is level (or not) and wobbling (or not). While the height of legs 104a, 104b 104c and 104d is not adjustable via a linear actuator, the height of the legs is still manually adjustable (e.g., by adjusting the distance that pads 105a, 105b, 105c, 105 d protrude from legs 104a, 104b, 104c and 104d, respectively). Hence, remediation measures to address a non-level or wobbling table can be
manually performed.
[0052] If not already apparent, power board 206 is configured to supply power to computing device 214, taptic engine 212 (electrical connection not depicted), wireless charger 220 and light sources 304a, 304b and 304c (electrical connections not depicted).
[0053] Figure 3 depicts the components of wireless charger 220 in more detail.
Wireless charger 220 may comprise a grid of wire coils 302. Within or proximate to the grid of wire coils 302 may be one or more light sources 304a, 304b and 304c (e.g., LEDs) that are used to generate the one or more light indicators 110a, 110b and 110c on the top surface of tabletop 102.
[0054] Figure 4A depicts a top perspective view of adjustable-height table 400 in a non-illuminated state. Adjustable-height table 400 may include tabletop 102 that is supported by two or more height-adjustable legs. In the embodiment depicted in Figure 4A, tabletop 102 is supported by four height-adjustable legs 404a, 404b, 404c and 404d, each positioned near a corner of tabletop 402. Similar to tabletop 102 of the fixed-height table 100, tabletop 402 may include an acrylic stone exterior with an internal cavity (not visible in Figure 4A).
[0055] Tabletop 402 may include one or more power outlets. In the embodiment of Figure 4A, the top surface of tabletop 402 includes universal power outlet 106a (capable of receiving electrical plugs adhering to European standards as well as US standards), and universal serial bus (USB) outlets 106b and 106c. More specifically, USB outlets 106b and 106c may be USB-C outlets.
[0056] Tabletop 402 may include one or more wireless charging areas located on a top surface of tabletop 102. When a mobile device (e.g., a smart phone, a tablet, etc.) is placed within or near the wireless charging area, a wireless charger disposed immediately beneath the wireless charging area is configured to wirelessly charge a battery of the mobile device.
In the embodiment of Figure 4A, three wireless charging area 108a, 108b and 108c are present on tabletop 402. The respective outlines of the wireless charging areas are depicted in broken line in Figure 4A to reflect an embodiment of the invention in which the respective boundaries of the wireless charging areas are not marked on the top surface of tabletop 402 (e.g., for aesthetic reasons). It is understood that the number of wireless charging areas may differ in another embodiment of the invention.
[0057] Figure 4B depicts a top perspective view of adjustable-height table 400 in an illuminated state. Upon a user performing a tap gesture (e.g., single tap, double tap in rapid succession, etc.) on a surface of tabletop 402, one or more light indicators may appear on the
top surface of tabletop 102. One or more light sources (not depicted in Figure 4B) may be present immediately below the top surface of the tabletop and shine light through a translucent portion of the top surface of tabletop 402 to generate the light indicators. In the embodiment depicted in Figure 4B, three (gesture-activated) light indicators 110a, 110b and 110c are present to indicate the location of wireless charging areas 108a, 108b and 108c, respectively. In one embodiment, each of the light indicators appears as a“+” symbol on the top surface of tabletop 402, but it is understood that other symbols, and shapes may be used instead of the“+” symbol.
[0058] In the embodiment depicted in Figure 4B, (gesture-activated) light indicators 410a, 410b and 410c are also present. Light indicator 410a may direct a user to the location of control element 416b on the back surface of tabletop 402 (depicted in the bottom view of Figure 4C) that can be used to raise the height of adjustable-height table 400. As a visual aid that is associated with the action of raising the height of adjustable-height table 400, light indicator 410a may be an“up arrow” symbol, as depicted. It is understood that other symbols are possible, such as“R” as an abbreviation for the action of“raise”.
[0059] In a similar fashion, light indicator 410b may direct a user to the location of control element 416a on the back surface of tabletop 402 (depicted in the bottom view of Figure 4C) that can be used to lower the height of adjustable-height table 400. As a visual aid that is associated with the action of lowering the height of adjustable-height table 400, light indicator 410b may be a“down arrow” symbol, as depicted. It is understood that other symbols are possible, such as“L” as an abbreviation for the action of“lower”.
[0060] Light indicator 410c may direct a user to the location of control element 116 on the back surface of tabletop 402 (depicted in the bottom view of Figure 4C) that can be used to enable and disable components involved with the sensing of the tap (or other) gesture. It is noted that an advantage to having control elements 116, 416a and 416b located on the back surface of tabletop 402 (as opposed to the top surface) is to decrease the chance of a user accidentally pressing the control elements, which would be more likely if such control elements were present on the top surface of tabletop 402.
[0061] Figure 4C depicts a bottom view of adjustable-height table 400. A bottom surface of tabletop 102 may include removable panel 118a and fixed panel 118b. Removable panel 118a may be secured to tabletop 402 using screws (not depicted). When removable panel 118a is removed from table 400, an internal cavity of table 400 may be accessed. A bottom surface of tabletop 402 may also include additional power outlets. In the embodiment
depicted in Figure 4C, two universal power outlets 106d and 106e are present. Power outlets 106d and 106e may be convenient for plugging in the power cable of a monitor and the power cable of a laptop or desktop computer.
[0062] A bottom surface of tabletop 402 may also include coupling mechanism 114 (e.g., a magnetic coupling mechanism) to releasably secure a hook to a bottom surface of tabletop 402. The hook (not depicted) may be a convenient accessory for a user to hang a backpack, handbag, scarf and/or hat, underneath tabletop 402. An advantage of a magnetic coupling mechanism (as opposed to other coupling mechanisms, such as using screws to attach a hook to the bottom surface of tabletop 402) is the ease of assembly (i.e., no screw driver or hand-held drill is needed).
[0063] Control elements 116, 416a and 416b were previously described above in association with the light elements 410a, 410b and 410c, so no additional description will be provided in association with these control elements for conciseness.
[0064] Figure 4D depicts a bottom perspective view of adjustable-height table 400.
The components that are visible in the bottom perspective view of adjustable-height table 400 are identical to the components that are visible in the bottom view of adjustable-height table 400, so no additional description will be provided in association with Figure 4D for conciseness.
[0065] Figure 4E depicts a sectional perspective view of adjustable-height table 400 with a cutting plane perpendicular to the plane of the top surface of the table. Cavity 120 is visible in the cross-sectional surface exposed in the sectional perspective view. Cavity 120 may include frame 122, which may be a grid made from a rigid material, such as aluminum. Frame 122 may provide structural integrity to tabletop 402 (e.g., preventing warping, bending, sagging, etc.).
[0066] Figure 5A depicts a top cross-sectional view of tabletop 402 (i.e., cross-section of tabletop 102 when viewed from the top), in which various internal components of tabletop 402 are visible. Many of the internal components of tabletop 402 are identical to those of tabletop 102, and hence its description will not be repeated for conciseness. Additional components included in tabletop 402 include, among other components, wires to electrically connect power board 206 and computing device 214 to each of the adjustable legs, light sources 504, and control elements 416a and 416b.
[0067] As shown in schematic diagram 550 of Figure 5B, wires may electrically connect power board 206 to each of adjustable legs 404a, 404b, 404c and 404d. Computing
device 214 may also be communicatively coupled to each of adjustable legs 404a, 404b, 404c and 404d, allowing computing device 214 to instruct the legs to extend and/or contract.
[0068] As shown in schematic diagram 550 of Figure 5B, wires may electrically connect power board 206 to light sources 504. Computing device 214 may also be communicatively coupled to light sources 504, allowing computing device to turn on and off light sources 504, in response to detected tap gestures (or other gestures).
[0069] As shown in schematic diagram 550 of Figure 5B, gyroscope 210 may be communicatively coupled to computing device 214, and can notify computing device 214 whether or not tabletop 402 is level and/or wobbling. In response to being notified that tabletop 204 is not level and/or not stable, computing device 214 may automatically transmit a control signal (e.g., height adjustment signal) to one or more of adjustable legs 404a, 404b, 404c and 404d in order to make the tabletop 204 more level or more stable.
[0070] As shown in schematic diagram 550 of Figure 5B, control elements 416a and 416b (e.g., up/down controls) may be communicatively coupled to computing device 214. In response to receiving a signal from control element 416a (e.g.,“down button”), computing device 214 may transmit a height adjustment signal to adjustable legs 404a, 404b, 404c and 404d requesting the legs to be shortened. Similarly, in response to receiving a signal from control element 416b (e.g.,“up button”), computing device 214 may transmit a height adjustment signal to adjustable legs 404a, 404b, 404c and 404d requesting the legs to be extended.
[0071] Figure 6A depicts a front view of the adjustable-height table in a lowered position, and Figure 6B depicts the front view of the adjustable-height table in a raised position.
[0072] Figure 7A depicts a cross-sectional view of adjustable-height leg 404a in a retracted position, Figure 7B depicts the cross-sectional view of adjustable-height leg 404a in an extended position.
[0073] Figure 8A depicts a cross-sectional view of a zoomed in portion of adjustable- height leg 404a in a retracted position, and Figure 8B depicts a cross-sectional view of a zoomed in portion of adjustable-height leg 404a in an extended position. The operation of adjustable-height leg 404a is described in association with Figures 8A and 8B. In one embodiment, adjustable-height leg 404a may comprise a linear actuator that is enclosed by a telescopic enclosure. In one embodiment, linear actuator may include motor 804, screw shaft 806, nut 810, inner tubular enclosure 812, and outer tubular enclosure 808. The operation of
the linear actuator is now described.
[0074] Motor 804 is configured to receive power from power board 206 and one or more control signals from computing device 214 via port 802. In response to receiving a first control signal, motor 804 may rotate screw shaft 806 in a clockwise (or counterclockwise direction). In response to receiving a second control signal, motor 804 may rotate screw shaft 806 in a counterclockwise (or clockwise direction). Screw shaft 806 may be threaded through a central opening of nut 810, which is fixedly secured to inner tubular enclosure 814. Inner tubular enclosure 814 has a vertically invariant elevation with respect to the
ground/floor on which adjustable-height table 400 rests (due to other supporting elements between inner tubular enclosure 814 and the ground/floor). Due to the fixed coupling between nut 810 and inner tubular enclosure 814, nut 810 importantly also has a vertically invariant elevation. Due to the vertically invariant elevation of nut 810, rotation of screw shaft causes motor 804 and outer tubular enclosure 808 (which is fixedly secured to motor 804) to either vertically translate upwards or downwards depending on the rotation direction of screw shaft 806.
[0075] In one embodiment, the telescopic enclosure comprises a plurality of bulbous members. In the preferred embodiment, telescopic enclosure includes thirteen bulbous members. For conciseness of explanation, two adjacent ones of the bulbous members will be described. A first bulbous member may comprise mushroom-stem portion 820a with a stem cavity, mushroom-cap portion 822a with a cap cavity, and coil spring 824a inserted (partially or fully) within the stem cavity of mushroom-stem portion 820a, depending on whether the leg is extended or contracted. A second bulbous member may comprise mushroom-stem portion 820b with a stem cavity, mushroom-cap portion 822b with a cap cavity, and coil spring 824b inserted (partially or fully) within the stem cavity of mushroom-stem portion 820b and the cap cavity of mushroom-cap portion 822a, depending on whether the leg is extended or contracted. In a compressed configuration of the telescopic enclosure, mushroom-stem portion 820b may be inserted into cap cavity of mushroom-cap portion 822a. In an elongated configuration of the telescopic enclosure, mushroom-stem portion 820b may be retracted from the cap cavity of mushroom-cap portion 822a.
[0076] Figure 9 depicts an exploded view of height-adjustable leg 404a and leg anchoring component 902. Leg anchoring component 902 may be secured to a top or bottom surface of fixed panel 118b using screws. Four screw holes 904a, 904b, 904c and 904d are illustrated in leg anchoring component 902, so in the embodiment of Figure 9, four screws
(not depicted) are used to secure leg anchoring component 902 to the top or bottom surface of fixed panel 118b.
[0077] Leg anchoring component 902 may include one or more radial pins 906 (e.g., radially protruding into the cavity of leg anchoring component 902) which are configured to be received in one or more L-shaped slots 908 of adjustable leg, in a bayonet mount fastening mechanism. In another embodiment (not depicted), the radial pins may instead be disposed on adjustable-height leg 404 (e.g., radially protruding outwards from the central axis of adjustable-height leg 404) and the L-shaped slots may be located on an inner side surface of leg anchoring component 902.
[0078] Figure 10 depicts a system diagram of adjustable-height table 400, in which computing device 214 is communicatively coupled to mobile device 270 (or a user’s laptop, desktop, etc.). It is understood that fixed-height table 100 may also be communicatively coupled to mobile device 270 in a similar fashion, but certain details described in Figure 10 may not apply to a fixed-height table (e.g., instruction to switch to a standing mode).
[0079] Computing device 214 may receive pressure readings from pressure sensors 208a, 208b, 208c and 208d and/or a signal from gyroscope 210. Based on such detected sensor signals, computing device 214 may determine, using machine learning, a posture of the user. The use of machine learning is described in more detail in Figure 11. In the illustrated example, the determined posture is then determined to deviate from a proper ergonomic position. As a result, a message to straighten the user’s back is transmitted from computing device 214 to mobile 270 and displayed thereon. Also in the illustrated example, based on the detected sensor signals, computing device 214 determines that the user has been sitting for more than one hour (e.g., there has been intermittent pressure on one or more of the pressure sensors for the last hour and the table is in a lowered position, implying a seating position). As a result, a message to switch to a standing mode is suggested to the user (i.e., suggestion to raise the height of the table).
[0080] Figure 11 depicts an example of how a posture of the user (whether ergonomic or not ergonomic) can be determined from a pressure pattern. In a training phase, known input/output pairs may be provided to a machine learning (abbreviated as“ML” in Figure 11) module of computing device 214. The input may include a pressure pattern, and the output may include whether the user’s posture conforms or does not conform with a proper ergonomic position, and in the case where it does not conform, the output may include the specific issue with the posture (e.g., slouching back, bent wrists, etc.). In the illustrated
example, pressure pattern 1 (input) is paired with an identification of a proper ergonomic position 1 (output); pressure pattern 2 (input) is paired with an identification of improper ergonomic position 1 (i.e., slouching back) (output); ... and pressure pattern 5 (input) is paired with an identification of improper ergonomic position 3 (i.e., bent wrists) (output). Based on such known input/output pairs, parameters of the machine learning module are optimized (e.g., via a backpropagation algorithm).
[0081] After the machine learning module has been trained in the training phase, the machine learning module may be used to evaluate the posture of the user based on detected pressure patterns (i.e., in a model application phase). In the example of Figure 11, a feedback module (abbreviated as FM) is also present, which takes the inferred posture from the machine learning module and determines an appropriate remediation measure (or if no remediation is needed, then compliments to the user on his or her proper posture). In the illustrated example, the machine learning module infers improper ergonomic position 1 (slouching back) based on pressure pattern 22 (which has some similarities to pressure pattern 2), and the feedback module determines the remediation measure of“Straighten your back” as a proper remediation measure for improper ergonomic position 1. Also in the illustrated example, the machine learning module infers proper ergonomic position 1 based on pressure pattern 31 (which has some similarities to pressure pattern 1), and the feedback module determines that words of encouragement (e.g.,“Well done, good posture!”) to the user are proper based on the user’s proper ergonomic position.
[0082] As is apparent from the foregoing discussion, aspects of the present invention involve the use of various computer systems and computer readable storage media having computer-readable instructions stored thereon. Figure 12 provides an example of a system 1200 that may be representative of any of the computing systems (e.g., computing device 214) discussed herein. Examples of system 1200 may include a smartphone, a desktop, a laptop, a mainframe computer, an embedded system, etc. Note, not all of the various computer systems have all of the features of system 900. For example, certain ones of the computer systems discussed above may not include a display inasmuch as the display function may be provided by a client computer communicatively coupled to the computer system or a display function may be unnecessary. Such details are not critical to the present invention.
[0083] System 1200 includes a bus 1202 or other communication mechanism for communicating information, and a processor 1204 coupled with the bus 1202 for processing
information. Computer system 1200 also includes a main memory 1206, such as a random access memory (RAM) or other dynamic storage device, coupled to the bus 1202 for storing information and instructions to be executed by processor 1204. Main memory 1206 also may be used for storing temporary variables or other intermediate information during execution of instructions to be executed by processor 1204. Computer system 1200 further includes a read only memory (ROM) 1208 or other static storage device coupled to the bus 1202 for storing static information and instructions for the processor 1204. A storage device 1210, for example a hard disk, flash memory -based storage medium, or other storage medium from which processor 1204 can read, is provided and coupled to the bus 1202 for storing information and instructions (e.g., operating systems, applications programs and the like).
[0084] Computer system 1200 may be coupled via the bus 1202 to a display 1212, such as a flat panel display, for displaying information to a computer user. An input device 1214, such as a keyboard including alphanumeric and other keys, may be coupled to the bus 1202 for communicating information and command selections to the processor 1204. Another type of user input device is cursor control device 1216, such as a mouse, a trackpad, or similar input device for communicating direction information and command selections to processor 1204 and for controlling cursor movement on the display 1212. Other user interface devices, such as microphones, speakers, etc. are not shown in detail but may be involved with the receipt of user input and/or presentation of output.
[0085] The processes referred to herein may be implemented by processor 1204 executing appropriate sequences of computer-readable instructions contained in main memory 1206. Such instructions may be read into main memory 1206 from another computer-readable medium, such as storage device 1210, and execution of the sequences of instructions contained in the main memory 1206 causes the processor 1204 to perform the associated actions. In alternative embodiments, hard-wired circuitry or firmware-controlled processing units may be used in place of or in combination with processor 1204 and its associated computer software instructions to implement the invention. The computer- readable instructions may be rendered in any computer language.
[0086] In general, all of the above process descriptions are meant to encompass any series of logical steps performed in a sequence to accomplish a given purpose, which is the hallmark of any computer-executable application. Unless specifically stated otherwise, it should be appreciated that throughout the description of the present invention, use of terms such as“processing”,“computing”,“calculating”,“determining”,“displaying”,“receiving”,
“transmitting” or the like, refer to the action and processes of an appropriately programmed computer system, such as computer system 1200 or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within its registers and memories into other data similarly represented as physical quantities within its memories or registers or other such information storage, transmission or display devices.
[0087] Computer system 1200 also includes a communication interface 1218 coupled to the bus 1202 Communication interface 1218 may provide a two-way data communication channel with a computer network, which provides connectivity to and among the various computer systems discussed above. For example, communication interface 1218 may be a local area network (LAN) card to provide a data communication connection to a compatible LAN, which itself is communicatively coupled to the Internet through one or more Internet service provider networks. The precise details of such communication paths are not critical to the present invention. What is important is that computer system 1200 can send and receive messages and data through the communication interface 1218 and in that way communicate with hosts accessible via the Internet. It is noted that the components of system 1200 may be located in a single device or located in a plurality of physically and/or geographically distributed devices.
